IMEEOVEMENT' 1N SEINGLE MACHINES;

@We flgemrle referat it in ttm tetter @anni 'nrt uniting part nf tige smite.

TO ALL WHOM IT MAY CONCERN: Y y y Be it knownthat'I, HENRY D. BARNE, of Fair Haven, in the county of New aven` and State of Connectieut, have invented a new Improvement inLShingle Machine; and do hereby declare the following, when taken in connection with the accompanying drawings and the`letters of reference marked thereon, to he afull, clear, and exa-et descriptionof the same, and which said drawingsconstitute part of this specification, and represent, in-.- v l Figure 1, a perspective view; and in Figures 2, 3, and 4, detached parts. v

This invention, though termed a. shingle machine, is applicable to the cutting of lath, veneers, Snc., and consists in the peculiar arrangeinent'ot` thecutt'er with the adjustable guide,which governs the thickness of the cut.

To enable others skilled in the art to construct and use my improvement, ,I will'proceed to describe the same, as illustratedl in the accompanying drawings. l

A is the framework, supporting, in inclined guides, B, ai carriage, C, to which the cutter D is attached. The said carriage is moved up and down in .the said guides by the application of power to the driving-shaft E, through the connecting-rod F; G is a platform fixed tothe guides B, or otherwise to the framework upon which thc material to be cut is placed. The cutter D, as will be seen in g. l, is set so that its edge is inclined, that is to say, higher at oneend from the platform than the other;y this, in connection with the inclination of the guides, gives to the cutter a drawing cut. Upon 'the carriage C, and back'of the cutter, is' fixed the adjustable guide H, adjustable upon a pivot at d, so as to turn tothe right or left, as denoted in 'red and b1ue,`g. 3 the distance of this swing is regulated by'the screws a. i Y

The operation for cutting shingles is as follows: `llhe block from which the shingles are to be cut is placed upon the platform G, and pressed uagainstthe guide H, and that en d of 'the block, say at the rig-ht hand, is pressed so as to turn the guide into the position denoted in blue,A fig. 3 then, as the-cutter comes down,.the shingle is cut in proper shape from the block.; and when the cutter is again raised, press upon the block so as I to turn the guide to the posit-ion denoted in red, hg. 3, and thesecond shingle will be cut, and so on, alternately pressing first the one end, and then lthe other, until the block' isA consumed.v Or if it is desireod to cut of a constant even thickness, turn both thescrews a, so as to hold the guide in the desired'xed position, say as die-'noted in black, fig. 3. Andfor different thicknesses, the support of the guide is slotted, 'so as to slide back and forth upon the pivot d, and be `fixed at that point. Back of the cutter, andto the carriage, is xed a spring,`I, and

between which and the cutter the shingle or thin gcut passes, and is'held until the cutter rises and descends to cut the second, when the second forces out the first. This is important ink orderto keep the machine clear between the block and the guide. By'this arrangement, it will be seen that the machine is'very much simplified, as all necessity of idogging the block is dispensed with, and'no more time is required inattending the machine than in automatic feeding, as .all machines require constant attendance vof one or more persons; but a saving of time is ma'de in my machine, both in introducing the block, and in rapidity of operation'. p

Having therefore thus fully described my invention, what I claim as new and useful, and desire to secure by Letters -Patent, s y l i The ycombination of the cutter D and the adjustable guide and the spring I, constructed and arranged to l operate substantially in the manner described.
